IMPROVEMENT IN TURN-BUTTONS FR STOVE--DOORS Specification forming partof Letters Patent No. 167,853, dated September-Q1, 1875; application ledJuly 6,1875. I

tain new and useful Improvements in Stove- Doors, of which the followingis a specification, reference being had to the accompanying drawing, inwhich- Figure l is a view of the outside, and Fig. 2 a view of theinside, of a stove-door and its casing fastened together, and embodyingthis invention. Fig. 3 is a partial section of a part of the same, on alarger scale, at the line z z,- and Fig. tis a like section, but withthe fastening turned so as to release the door. Fig. 5 is a partialsection of the same, on the saine enlarged scale, at the line y' y inFigs. 2 and 3, and viewed in the direction of the arrow 5v. Figs. 6, 7,8, 9, and 10 are views of parts of' the device shown in Figs. 3, 4, and5. Fig. 1l is a sectional view of a part of a stove-door secured toitscasing, and showing a portion of my invention in a modilied form; andFig. 12 isA a plan of a part of the same below the line w w. Fig. 13 isa sectional view of a part of a stove-door and its casing securedtogether, and showing one form of a part of this invention. Fig. 14 is asectional view of a part of va stove-door and its casing, securedtogether' by a turn-button of the kindheretofore commonly used.

Like letters refer to like parts in the dierent figures.

ln the turn-button heretofore often used on stove-doors, and shown inFig. 14, a round stem extends through, and turns in, a socket throughthe door, and has a hand-piece and collar fast on the stem on the outerside of the door, and a finger fast on the stem on the inner side of thedoor, and arranged to engage with, and be disengaged from, an inclinedbearing on the casing of the door, so

Y as to thereby fasten and unfasten the door on the inside by turningthe stein by its handpiece on the outside. In such cases the collar endof the hand-piece bears directly and rigidly against the outer sideofthe door, and the button-nger is rigid o'n the stem, so that it isvery difficult to fit the same to the door and to the inger-bearing onthe door-Casin g, and so that the device turns hard in fastening thedoor, and will not hold the door' tightly closed whenever the parts arenot very accurately' iitted together, or become much Worn; and, byreason of the direct bearing of the handpiece collar against the door,the handpiece is liable to be highly heated, so as to burn the hand of aperson taking hold of it in fastening and unfastening the door.

To overcome or lessen the aforesaid defects is the primary object ofthis invention; and I accomplish that object by having the stein Aextend through, andformed so as'toturn and slide endwise within, thesocket b through the door C, and with the iin ger D fast on the stein onthe inner side of the door, and the collar E and hand-piece F fast onthe stem outside and away froml the door, and with a spring, G,surrounding the stem, and compressed between and against the door andthe collar on the stein, and the whole constructed andarranged so thatvery little care or accuracy is required in iitting the parts together,and so that, by reason of the yielding of the spring Gr, and theendwiseInovability of the stern A, the latter can be easily turned so as toengage the finger D with any suitable inclined part or bearing h on thedoor-casing I, and so that the reaction of the compressed spring Gr willthen keep the door tightly closed, but will still permit the stem A tobe easily turned, so as to release the finger D from the bearing h, andso that the spring G shall also constantly isolate the collar E andhand-piece F from the door C, and thereby effectually lessen the heatingof the hand-piece.

Fig. 13 shows the spring G exposed to View, and unconned on its outersides, andwith the stem A supported wholly by the one socket b near oneend of the stem, so that the spring G, when formed of ordinary roughsteel wire, as usual,.would present an unsightly appearance inconnection with the usually polished and plated hand-piece F, andthestem A would be liable to wabble unless the socket b should be madelonger than is desirable.

To overcome those defects is the object of a part of my invention; and Iaccomplish that object by means of the shield-piece or socket J, whichextends outward from the door, and incloses the 'spring Gr laterally,and forms a lateral socket-bearin g at k for the collar E of the stem A,so that the latter may be snpported by the two bearings, b and 7c, oneat each end of the spring.

In Fig. 11 the part J is shown4 in one and `the same piece with the bodyof the door C,

, thereby produce friction, and somewhat affect the strength or actionof the spring by torsion of the latter.

To overcome those. defects is the principal objectof a further part ofthis invention, which I attain by making the shield-socket J, socket b,and bearing fm, for the inner end of the spring G, all in one separatethimble-piece, L, and tted into, but not quite through, the socket n inthe door-body, and retained, so that it may turn therein, by thereaction of the compressed spring G in connection with the stem A, andits finger D bearing against they inner rim o of the socket n, as shownin Fig. 4, or against the bearing h of the doorcasing, as represented inFigs. 2, 3, and 5.

Inv Figs. 6, 7, 8, and 9 the finger D, thimble L, spring Gr, and stem A,with its collar E and halrlid-piece F, are shown separate from` each oter.

In Fig. 10 the stem is inserted in the spring I in the thirnble L readyto be inserted in the socket u in the door-body, and after suchinsertion the iinger D is to be fastened to the inner part of the stem Aby riveting down the end of the latter, as indicated at p in Figs. 3, 4,5, and 13, or by a screw and nut, as represented at q in Figs. 1l and12, or by any other suitable means.

What I claim as my invention is- 1. In combination with a stove-doorhaving the socket b therein, and door-casing having the button-bearinghthereon, the turningand endwise-moving stem A, with its button-iinger D,collar E, hand-piece F, and spring G, all arranged to operate as shownand described.

Y2. In combination with a door having the socket b, and doorcasinghaving the finger! bearing h, the turning and sliding stein A,

with its nger D, collar E, and hand-piece F, the spring Gr and theshield-socket J, all arranged together substantially as shown `andspecified.

3. In combination with a door having the socket b in a turning thimble,L, Fig. 3, in the socket n in the door, the stem A, with its finger D,collar E, and hand-piece F, and the spring Gr, surrounded with thecollar by the thimble, and all arranged to operate as shown anddescribed.
